    Abstract: The present disclosure relates to a method of fabricating a thermoelectric device. The method includes disposing a metal layer on a dielectric layer to form a sub-assembly, forming patterned circuits on the metal layer, forming blind vias in the dielectric layer, fabricating first thermoelectric elements in a first series of blind vias, and fabricating second thermoelectric elements in a second series of blind vias to form thermoelectric units with the first thermoelectric elements and the patterned circuits. The sub-assembly is configured to be joined to an adjacent sub-assembly along a first direction, and the first and second thermoelectric elements of each thermoelectric unit are aligned in a second direction substantially perpendicular to the first direction. The present disclosure further relates to a thermoelectric device which includes a plurality of thermoelectric units forming a strip extending in a first direction.

    Abstract: Passive cooling article (120) includes a plurality of first elements (122) defining a high absorbance in the atmospheric window wavelength range and defining high average reflectance in the solar wavelength range and a plurality of second elements (124) defining a low absorbance in the atmospheric window wavelength range and defining high average reflectance in the solar wavelength range, wherein the plurality of first (122) and second (124) elements are interspersed to form a major structure having a first major surface (130) comprising the first element outer surfaces (126) and the second element outer surfaces (128), wherein the first element outer surfaces (126) face a first direction toward a first end region (136) of the major structure (130) and the second element outer surfaces (128) face a second direction toward a second end region (136) of the major structure. The article (120) may be applied to a substrate (104), for example, on a generally vertical surface of a vehicle or stationary structure.
